Abstract (en)
[origin: US4723249A] A frequency stabilized pulsed laser system useful for heterodynes telemetry comprises an amplifying medium (21), between a mirror (27) and a four wave mixing phase conjugate mirror (30). The non linear medium of mirror (30) is a part of the laser medium (21), because of the presence of a lens (31). The mirror (30) is pumped by the direct beam of a continuous laser (29) and the reflected beam from the mirror (27). The light emission of the laser exits through an optical isolator (28).
